Specification of Letters Patent.

Patented June 1, 1915.

Application filed August 19, 1912, Serial No. 715,906. Renewed December 4, 1914. Serial No. 875,533.

To all whom it may concern:

Be it known that I, FRANK E'. SIMPKINS, a resident of Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Tube-Rolling Mills, of which the following is a specification. v j r This invention relates to rolling mills, and has particular reference toa Inill forcrossrolling such as is generally used for rolling seamless tubes, and the primary object .is to provide simple and effi'cient roll mountings, together with improved means for adjusting the rolls relatively to each other and .to the roll pass, the several adjustments being un der accurate control and of such scope as to meet the varying requirements peculiarto cross-rolling. 4 r I A further object is to provide a frame of improved construction in which the roll mountings are arranged.

In the accompanying drawings, Figure. 1 is a View of the improved mill, one-half thereof being shown in top plan and the other half illustrating one of the roll mountings insectional plan on line 1-1 of Fig. 2, and with the upper portions of the frame sides removed to illustrate the slidable rollsupportingcarriage. Fig.2 is an elevation of the mill, one-half thereof being a front elevation, and the other half a vertical section on line,22 of Fig.1. Figs. 3 and 4; are sectional elevations on lines 3-3 and 4.4, respectively, of Fig. 1. v Fig. 5 is a section of the frame and carriage,in the plane of line 22 of Fig. 1 with the roll mounting removed from the carriage. Fig. 6 is a sectionaldetail of the gearing for adjusting the roll about a horizontal axis.

The portions of the mill at opposite sides of the roll pass are .duplicates .one of the other save "for the reversely positioned rolls which result in cross-rolling,.. and it will therefore be understood thatthe following description of the roll mountings and adjustments phrased in the sin 'ularis applicable to the mechanism at either side 0 the ass.

p The mill is preferably located one heavy foundation plate 2 formed. with marginal uprightlugs 3 between; which the lower longitudinal members 4 of the mainframe are secured by wedges 5. The longitudinal sides of each half .of the fralneconsist each of the bottom beam 4 above referred to and a top beam 6, the beams being secured tofront, and a similar bolt 9 at the rear.

The under faces .of opposite beams 6 are recessed on their inner sides to form longitudinal slideways 10 for the plate-like carriage 11 which carries the roll mounting. The carriage is adjusted toward and from the roll, pass by the hand-operated screw shaft 12, and after being adjusted it is secured in slideways 10 against vertical displacement by the elongated longitudinally movable wedges 13 each formed with a boltlike extension 14 which projects through the end of the frame where it is provided with an adjusting nut 15.

The inner edge 16 of carriage 11 is of semi-circular form to embrace base 17 of oil'- cular casing 18, the latter being semi-circular in the plane of the carriage as shown in Fig. 1, and the casing is supported on the carriage by the semi-circular flange 19, the flange being formed with concentrically grooved slots 20 to receive clamping bolts 21 rojected upwardly from the carriage.

he face of each casing 18 adjacent the roll pass is formed with a bearing recess 22 -which is circular around a horizontal axis and the recess is stepped into reduced diameters from front to rear, as shown. Fitting this recess is the circular and complementarily stepped head 23 which is recessed on its front face at 21 to receive the roll 25, the spindle 26 of the latter being journaled on the front face of the head, as shown.

A bolt passage extends rearwardly through the center of head 23 and through casingv l8, and arranged therein is clamping bolt 27 provided with a nut at its outer end on the exterior of the casing 18for securing or clamping head 23 after it has been adjusted as desired.

Head 23 is adjustable about a horizontal axisdefined by bolt 27for varying the vertical inclination of the roll, and with the clamping bolt slackened this adjustment is accomplished by the worm gear 28 mounted preferablyin the top of casing 18 and meshmg with gear teeth 29 on head 23, Fig. 6, the spindle of worm 28 having a squared extremity to, receive a a wrench. The worm gear is in itself a lock for the head, and it, together with the clamping bolt 27, securely hold the head with the roll in the angular position to which it is adjusted.

For adjusting the mounting about a vertical axis as required for adjusting the roll face laterally with relation to the pass, Wrench-turned screw-bolts 30 have swivel 7 connections with casing 18, as indicated at 31, and extend outwardly through nuts 32 fixed to carriage 11 so that upon turning the rods casing 18 may be adjusted on carriage 11 about a vertical axis and then secured by blots 21.

The several adjustments are effected with mechanical precision and are positively maintained and provide for every roll adjustment necessary for cross-rolling.

' I claim 1. In a mill for cross rolling, the combination of opposed rolls normally in fixed position relatively to the pass formed thereby, and a normally fixed support for each roll adjustable about axes disposed at right angles to each other.

2. In a mill for cross rolling, the combination of opposed rolls normally in fixed position relatively to the pass formed thereby, and a normally fixed support for each roll adjustable about a vertical axis which intersects the roll.

8. In a mill for cross rolling, the combination of opposed rolls normally in fixed position relatlvely to the pass formed thereby, and a normally fixed support for each roll adjustable about a vertical axis and also about a horizontal axis.

4. In a mill for cross rolling, the combination of opposed rolls normally in fixed position to form a horizontal roll pass, and a normally fixed support for each roll adjustable about a perpendicular axis which intersects the roll.

5. In a mill for cross rolling, the combination of opposed rolls normally in fixed position to form a horizontal roll pass, and a normally fixed support for each roll with each roll adjustable about axes disposed at right angles to each other and with one of said axes. disposed at right angles to the axis of the roll pass.

6. In a mill for cross rolling, the combination of opposed rolls normally in fixed position relatively to the pass formed thereby, a normally fixed support adjustable about axes disposed at right angles to each other, and means for adjusting each roll support bodily toward and away from the other support.

7. In a mill for cross rolling, the combination of normally fixed supports at opposite sides of a roll pass with each support formed with a curved seat which faces the pass, normally fixed roll mountings adjustable in said seats about horizontal axes, and opposed rolls journaled in the roll mountings.
